I have set up my document with the following settings:
Gutter 0.89 cm
However the gutter appears to be on the wrong side i.e. when I look at the double page spread the outer margins are wider than the inner ones despite the fact that the inside margin plus gutter should make it wider. The mistake also shows up when I export a PDF. If this rings any bells let me know!
The gutter refers to space between columns, not the gutter of the spread.
If you have a two column layout, the gutter size would be what you entered.
You can even see on the New Document dialog box that the Columns is grouped with the Gutteer Setting
Thanks very much - this clears up my problem!
